Answer 2

Answer:

Option D. 4/5

Step-by-step explanation:

we know that

The probability of scoring 1, 3, or 5 points with one randomly thrown dart is equal to divide the area of the largest circle by the area of the square game board

step 1

Find the area of the square game board

$A=b^{2}$

we have

$b=20\ cm$

substitute

$A=20^{2}$

$A=400\ cm^{2}$

step 2

Find the probability

$P=320/400$

$P=0.8=8/10=4/5$
